Update with my sitiuation:
When I want to add the mention user (@username) function to My Q2A ,finally I found out this q2a plugin:
https://github.com/ProThoughts/q2a-hashtagger
I found it work with no-sapce username like "@abc" or "@a-b-c" but not "@a b c".
I read the code , I found that in "qa-hashtagger.php" , line 378 and 383 , we see the match rule as follow:
$row['content'] = $this->preg_call('%@(?P<name>[\w\-]+)%u', 'build_user_link', $row['content']);
We would like to add the space ("\ ") like this:
$row['content'] = $this->preg_call('%@(?P<name>[\w\-\ ]+)%u', 'build_user_link', $row['content']);
It works, one thing:
I find out that the style of content will lose and become one line, like :
abc
def
@solidChen
become to : abc def @solidChen
But, after testing , I found out that if we use the "Insert a quote" (on Q2A's editor,in Chinese is "引用段落") and write "@solidChen" inside , style keeps fine.
Other bugs? I don't know yet :)
